Question 12 of 40
What is the highest number of electrons that can be in electron shell 2?

8

Explanation:

the 1st shell closer to the nucleus is 2

2nd 8

3rd 8 etc

In shell to or L shell can only afford 8 electrons according to the OCTECT rule. Also, the outermost shell of any atom can only afford 8 electrons according to the octect rule

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
